Always use reputable community forums and verified tools if you are dumping your own discs into PKG format.

From the perspective of game preservation, the ability to manage PKG files is a significant milestone. As the console market moves aggressively toward digital-only releases, the industry faces a crisis of preservation. Physical media can degrade, and digital storefronts can be shuttered, as seen with the closure of the PlayStation Store for older legacy consoles. The ability to back up PS4 software into PKG files offers a safety net, ensuring that games are not lost to time or corporate server shutdowns. For enthusiasts, the installation of custom firmware allows for the running of homebrew applications, emulators for older systems, and the transfer of legitimate game backups to larger internal or external drives, breathing new life into aging hardware.
